A new firmware version has released for the FC Mumu Pro: E13.4.15. It's a mixed bag: Gimmick! has been fixed and is now playable VRC6 and VRC7 games boot now, and play expansion audio. It's still muffled compared to EDN8 Very preliminary save state support has been added Select + Right to...

No concrete timeline. When it is restocked, it'll be the newest revision which includes an ISL9122A for analog fan control.

Wow, it came out great! Incredibly clean internals given the size, and the easily accessible microSD with a push-push slot is a nice touch. I'd love to see the Thundervolt app running on it.

Your resanded mobo looks better, but resanding shouldn't be done blindly. If you download the Compendium you'll notice the 1.8V plane (light green) doesn't even intersect your trim line! So there is no way the board edges could be causing this short. My money is on a cracked ceramic...

Just checking... what's the exact resistance you're measuring between 1.8V and GND, with nothing else connected to the motherboard? Continuity mode can be deceiving on some multimeters. ~36Ω between 1.8V and GND is normal.

Hard to beat the convenience of that GLC-1239 board's solder jumpers. Looks like it uses a Monolithic Power MP2315. That's an obsolete part, and the board is not optimized for low-voltage output. The datasheet recommends a ~1.8uH inductor for Vout < 2V, while this board uses 4.7uH, meaning for a...

OP has been updated with a Google Drive link!

GC2Wiimote doesn't work with Rhythm Heaven Fever and a few other games. Here's an incomplete list: - Rhythm Heaven Fever - Warioware Shake It - Poképark and Poképark 2 - Pokémon Battle Revolution - No More Heroes 2 - The Last Story - Monster Hunter Tri - Lego Batman 2 - Phineas and Ferb

The FC Mumu Pro is a brand new, fully-original Famicom flashcart designed by 沐沐 (Mumu) for the Chinese market. Currently, it's only available on Taobao and Xianyu, and costs 388 RMB (57USD). Because it's China-only, there's no English documentation of its capabilities. So this post will...

The RG40XXV screen as seen in this thread (laminated 4" 640x480 with 39-pin ZIF, needs SPI init) is now available directly from Anbernic for $28: https://anbernic.com/products/accessories?variant=47008062898433 Note that there's a limit of 3pcs per order and shipping is $35. Not ideal, but...

Is this a joke? @loopj used an AI-generated banner image in his 2024 contest entry and won second place. I really hope the staff walks this decision back. AI is becoming more and more commonplace in tech hobby spaces (just look at JoypadOS) and a stance like this is just going to result in less...

Incredible work and you're a legend for open sourcing it.

Awesome to see a Wii U portable worklog! While the WUP-50's plugged vias are more difficult to deal with, they're definitely not finicky enough to warrant the ~11W hit of using a WUP-01/30/40. That's two whole Wiis worth of additional heat you have to dissipate, not to mention way more voltage...
